Abstract
The utility model relates to an improved anticorrosion dropper. The dropper comprises a dropper body, wherein a rubber dropping capsule is arranged on the dropper body; a nozzle plug is arranged on the joint of the dropper body and the rubber dropping capsule, and provided with an inverted cone shape through hole which is communicated with the dropper body and the rubber dropping capsule; the dropper body under the nozzle plug is of a gourd shape; the air flow can smoothly enter and exit the rubber dropping capsule to absorb reagent due to the arrangement of the nozzle plug, the chemical reagent is prevented from returning to the rubber dropper capsule caused by evaporation of the chemical reagent or misoperation, and chemical reagent can be stored into the gourd-shaped dropper body, so that the chemical reagent hardly enters the rubber dropping capsule, the service life of the rubber dropping capsule is prolonged, and the use is easy and convenient.
Description
Technical field
The utility model relates to a kind of teaching aid, relates to a kind of dropper of doing experiment usefulness specifically.
Background technology
Dropper is an instrument commonly used in the education experiment, because the dropper structural reason, chemical reagent enters into rubber easily and drips capsule corrosion rubber and drip capsule, shortens the service life of dropper.
The utility model content
The problem that the utility model will solve is to above problem, provides a kind of rubber that can prolong to drip the capsule improved anticorrosion dropper in service life.
For addressing the above problem; The technical scheme that the utility model adopted is: improved anticorrosion dropper; Comprise the dropper body, said dropper body is provided with rubber and drips capsule, and the junction that said dropper body and said rubber drip capsule is provided with mouth of pipe plug; The said mouth of pipe is provided with said dropper body beyond the Great Wall and drips the back taper through hole that capsule is communicated with said rubber, and the said dropper body of the below of said mouth of pipe plug is two spherical cucurbit shapes.
The utility model is taked above technical scheme; Have the following advantages: improved anticorrosion dropper; Comprise the dropper body, said dropper body is provided with rubber and drips capsule, and the junction that said dropper body and said rubber drip capsule is provided with mouth of pipe plug; The said mouth of pipe is provided with said dropper body beyond the Great Wall and drips the back taper through hole that capsule is communicated with said rubber, and the said dropper body of the below of said mouth of pipe plug is two spherical cucurbit shapes; The setting of mouth of pipe plug has guaranteed that not only air-flow can pass in and out rubber smoothly and drip capsule to draw reagent; Prevented the chemical reagent evaporation again or dripped capsule because of operate miss lets the chemical reagent refluence enter into rubber; The lageniform dropper body of two spheries chemical reagent can be stored into wherein; Drip capsule thereby be difficult to enter into rubber, prolonged the service life that rubber drips capsule, easy to use.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure: 1-dropper body; The two spherical cucurbit shapes of 11-; 2-rubber drips capsule; 3-mouth of pipe plug; 31-back taper through hole.
The specific embodiment
Embodiment: improved anticorrosion dropper; Comprise dropper body 1; Said dropper body 1 is provided with rubber and drips capsule 2; Said dropper body 1 is provided with mouth of pipe plug 3 with the junction that said rubber drips capsule 2, and said mouth of pipe plug 3 is provided with said dropper body 1 and drips the back taper through hole 31 that capsule 2 is communicated with said rubber, and the said dropper body 1 of the below of said mouth of pipe plug 3 is two spherical cucurbit shapes 11; The setting of mouth of pipe plug 3 has guaranteed that not only air-flow can pass in and out rubber smoothly and drip capsule 2 to draw reagent; Prevented the chemical reagent evaporation again or dripped capsule 2 because of operate miss lets the chemical reagent refluence enter into rubber; Dropper body 1 chemical reagent of two spherical cucurbit shapes 11 can be stored into wherein; Drip capsule 2 thereby be difficult to enter into rubber, prolonged the service life that rubber drips capsule 2, easy to use.
